Damn snakes took my eggs.
Like Pamela mentioned below, some sounds would really elevate this. Just a basic jump "bwoooOOP" and a "bading!" sound for collecting eggs.
Massive props for making your own graphics. You could easily just have grabbed some pre-made snakes and chicken but you didn't. I love that. I had some issues with the snakes in this area:
The snakes are a little too wide and the jump is a little too short to pass them consistently. As seen in the top of this image, the eggs can land on the snakes and just make them impossible to collect. The first thing you see when you start the game is an egg falling. Having them be unaffected by gravity or other physics would be better, so you don't get these annoying interactions.
A very minor nitpick: the tree is baaasically the same color as the player character, which makes them blend together as you in front of it. I'd probably make the chicken brighter, more of a beige, or make the tree darker to keep the focus on the action in the foreground.
I took a look because I'm a little creeper, and noticed that you created your Itch account like a week ago. Welcome! I hope you keep making games and participating in game jams, I'd love to see some more stuff from you.
